APFormer GOP vice presidential nominee Sarah Palin has not yet been invited to the Republican National Convention in Tampa.

Sarah Palin says she still waiting for an invite from Mitt Romney to attend this summer's Republican National Convention in Tampa.

The former GOP vice presidential nominee could be waiting a while. As this week's Newsweek pointed out, Palin has been critical of Romney since she flirted with the idea of running for president last summer. She has questioned his conservatism and held off on fully endorsing the former Massachusetts governor.

"What can I say?" Palin told Newsweek in an email. "I'm sure I'm not the only one accepting consequences for calling out both sides of the aisle for spending too much money, putting us on the road to bankruptcy, and engaging in crony capitalism."

If Palin remains uninvited, it'll only be the third time the prior cycle's GOP vice presidential nominee was denied a chance to speak at the RNC, CBS News reports. Jack Kemp did not receive a speaking slot in 2000, and Bob Dole missed out on speaking in 1980 because he attended the convention as a candidate still actively seeking the nomination.

"In accepting those consequences, one must remember this isn't Sadie Hawkins and you don't invite yourself and a date to the Big Dance," Palin added.

Newsweek speculated that perhaps Palin's chances of going rogue while speaking at the convention are too great for a campaign that "prides itself on a slavish adherence to script." While the magazine didn't get a response from the Romney campaign regarding Palin's invitation, one adviser associated with the campaign said that Palin may be prohibited from speaking under her contract with Fox News.

"It's true I'm prohibited from doing some things," Palin said. "but this is the first I've heard anyone suggest that as an excuse, er, reason to stay away from engaging in the presidential race. I'm quite confident Fox's top brass would never strip anyone of their First Amendment rights in this regard."

Fox told Newsweek that Palin's contract would not prohibit her from speaking at the convention if she asked for permission.

Jenny Beth Martin, head of the Tea Party Patriots, thinks inviting Palin to speak would "rile up" Romney's base and "make them enthusiastic." "And I don't mean just the Tea Party. I mean die-hard Republicans," she told Newsweek.

According to a Marist-McClatchy poll released on Monday, Obama leads Romney 48 percent to 46 percent among national registered voters.

Regardless of whether or not she is invited, Palin said she remains committed to "motivating the grassroots made up of independents and constitutional conservatives" to defeat President Obama on election day.
